Configuring Lazy Communication 

Use

The lazy communication mechanism is used automatically by the Cluster Manager to quickly exchange large amounts of information between two server processes without using the message server as an intermediary.

By default, lazy communication is enabled only for a predefined list of services (the list is stored in the lazy.exclusive.list property) and disabled for the remaining services.

We recommend that you do not modify the default lazy communication settings unless you are advised to do so by SAP Support.
